To all vwhom it may concer/i.'

Be it known that we, ERNST D. MOORE, a citizen ofthe United States, and STANLEY L. FISHER, a subject of the King of Great Britain, both residing in Saybrook, county of Middlesex, and Stat-e of Connecticut, have invented certain new and useful Improvements in Sheet-lVnding Mechanism .for Player-Pianos, of which the following is a full, clear, and exact description.

This invent-ion relates to note sheet centering mechanism for player pianos, and one of the objects Of the invention 1s the provision of means for causing the sheet to be wound up tightly and in a proper manner on the take-up spool so that when the sheet is re-rolled on the music roll it will be so positioned on t-he latter as to induce proper rendition the next time the roll is played. 20 More especially, ouil object is to provide means for exerting pressure on the edges of the note sheet as it is wound on the take up spool in such a manner as to prevent the deviation of the sheet from its proper path, together' with means for regulating the lpressure on. the edges of the note sheet and relie-ving thc pressure when a certain maximum is attained. Devices for exerting pressure on the edges of the sheet as it winds not carefully controlled the edges of the sheet quickly become torn and mutilated. ln accordance with our invention, however, the sheet is wound up truly on t-he take-up spool without mutilation or damage.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings` Figure 1 is a front elevation of note sheet centeringl mechanism embodying our invention, with certain parts'broken away, the music roll being in the playing position;

Fig. 2 is a rear elevation of the mechanisni, showing the music roll holding device in the position which it assumes when the music roll is removed;

Fig, 3 is a pla-n view of the supporting means for the music roll, the top of the spool box being omitted;

on the take-up spool have been heretoforedevised, but where the lpressure devices are Figs. 4 and 5 are detail views of the music roll-supporting spindles; and

Figs. (i and 7 are details of the connection between the pneumatic and the actuating levers for the pressure devices associated with the take-up spool.

The spool box 10 is of the usual type and supports the customary tracker bar 11 in the ordinary manner. This tracker bar may be fixed in position by screws 12, as shown in the drawings, or, in some cases, may be mounted to allow adjustment laterally' of the box by means well known inthe art. The music roll 13 carrying the note sheet 1st is mounted above the tracker bar in the customary location by means of spindles 15,

16, and the take-up spool 1T is located in` the customary manner beneath the tracker bar and support-ed by spindles 1S, 19. all of said spindles having bearings in the side walls of the box, as shown. i

Referring now to the mechanism for supporting and centering the music roll 13, it will be observed that the spindle 15 is in the nature of an enlarged hub on a stem 15, said spindle or hub being located at the inner face of the box wall, and guided for lengthwise movement in a bushing 20 in said wall, as shown in Fig. al. At its inner end, the spindle 15 is 'provided with a lat erally projecting flange or collar 251 having a vertical face disposed toward the adjacent music roll head 13. Projecting inwardly from the collar 21 is a centering projection or boss with an inclined periphery adapted to enter a correspondingly shaped but larger recess 23 in the roll head 131. The arrangement is such that while the vertical inner surface on the collar 21 makes contact with the end face of the roll head 13, the boss 29. is of such size and shape as not to bottom in the recess or socket The spindle 1G is generally similar to the spindle 15, being mounted on a stem 1621 and guided for endwise movement in a bushing 2l of the box wall. Near the inner ond of the spindle is a collar 25 similar to the collar 21 and having a vertical face to contact with the. end surface of the roll head 13. Projecting from the inner end of the spindle 16 is the usual driving lip Q6 adapted to project into a socket 27 in the roll head 18'),

but the arrangement is such that while the Vinner face of the collar 25 engages vthe end face of the roll head 13", the lip 26 and the adjacent spindle end do not bottom in the socket 27. Thus, it will be understood Vthat when the music roll is inserted between the spindles 15, 16, said spindles will contact only with the end surfaces of the corresponding heads of the music roll. rlhe collars 21, 25 prevent the spindles from engaging the bottoms of the respective sockets, which is a feature ot z idvantage` that is more particularly explained hereinafter. A

knurledv collar 28 on the spindle 16 facilitates the turning of said spindle by hand so as to engage the lip 26 non-rotatively with a rectangularportion of ,the socket 27 in the usual manner so that the roll may be driven by the rotation of the spindle 16.

The music roll-is driven from the stem kor shaftl"L bymeans of suitable connections with an appropriate motor (not shown),

whichV motor is also operatively connectedv with the'shatt or spindle 19 or" the take-up roll so as to drive` the latter in the usual manner. e'

' 'The collars 21, 25 of the respective rollsupporting spindles are yieldingly heldin contact withy the Yrr-ispective roll heads by mechanism which may be constructed substantially as follows: On the stem 4orshaft 15a at a point outside of the spool boxare mounted two vspaced collars 29, 30, which may be secured on -the `shaft by means ot screws, as shown; Collars 31, 32 are mount ed on the shaft 16?V in a similar manner. The collars 29, 31 nearestithe spool box are adaptedto abut against the respective side walls of thev boX so as to limit the inward movement of the respective spindles, and

, these collars are so adjusted that when they V'contactwithz the respective walls of the box or other suitable abutments, the V collars or shoulders 21, 25 are equidistant from the 45V center of the'spool box, and are slightly nearer to 'each other than are the outersur-v Vfaces of the music rollheads.. In other words, said ycollars'are spaced apart at a dista-nce which is less than the maximum length of the music roll. 'Between the collars 29, 30, a bar 33 engages the shaft 15a by means of an inturned end portion 34 which is adapted to abut the collar 29 in order to move the shaft toward the music roll and to abut the collar 30 in order to move the shaft away from the music roll. A similar bar 35l has an inturned end portion 36 embracing the shaft 16a between the collars 31, 32. `The bars 33, 35 are` pivoted at 37, 38 respectivelyfto a lever 39 'which is swiveled to the back of the boX at 40. The swivel mounting 4 0 of lever 39 is centrally located between the pivots 37, 33 so as to equalize the movement of the two spindles 15, 16 and insure their having. a symmetrical relation to a predetermined center line at all times,

irrespective of the lengthwise adjustment ofV leased, the spring .41 returns the parts to the normal position 1n an obvious manner so that the spindles are at the limit of theirI inward movement with the collars 29, 31 in abutment with the sides of the box. When newA music roll is to be inserted, the spindlesy are moved away from each other, :tor eX- ample, by grasping the knurled collar 23 on spindleV 16, and when the collars 21, 25 ot the respective spindles are engaged with theend faces of the roll heads in the mannei previously described, it will be found that the note sheet is symmetrically located with respect to a given center line, such as the centerline of the music box, because in all music rolls with which we are familiar the two headsare symmetrically forme-d to the extent that the end surfaces for engaging thecollars 21, 25 are equidistant from the center ofthe note sheet. lt will be understood, therefore, that the roll centering device vjust described can be used to center music rolls of many different types without regard to the depth of the sockets in theroll.

heads soi long as such sockets have the usual ing the socket-engagingY projections on the spindles VVsoshallow thatthey will not engage the bottoms of the sockets of any or the standard music rolls.

. If, after assembling, it is foundthat the spindles do not have the proper symmetrical relation to a. predetermined center, the neces sary correction can be effected by shifting the shaft collars in an obvious manner.V The collars on each shaft should obviously be spaced apart at ak sufficient distance to permit the necessary swinging movement of the bars33, 3 5.A Ordinarily, the center with re spect to -which the collars 21, 25 are symmetricalv is in a. vertical plane passing through the center of the tracker bar scale, e'. e., the series of perforations in the tracker bar corresponding to the number of notes ot' the piano which are Vto be played, but naturally if the tracker bar is to be adjusted out of its normal position, say for the purs pose of'transposing the key', the music roll will be longitudinally displaced with respect to the tracker bar.

Referring now to the take-up spool 17, it will be observed that thesame is provided with movable end flanges 44 adapted to make contact with the edges of the note sheet 14. In the particular form illustrated, these anges 44 are normally pressed away from the ends of the spool proper by coil springs 45 (of which only one is shown) located in suitable sockets'in the end of the spool and embracing the respective spindle or shaft portions 18, 19. The take-up spool is prevented from endwise movement by collars 46 screwed on the spindles 18, 19 at the inner portion of the box, said collars abutting against bushings 47 which form bearings for the spindles. These collars 46 are adjustable in an obvious manner so that the take-up spool may be adjusted laterally in the box. lEach flange 44 has a hubV portion 4S contacted by the forked portion 49 of an elbow lever 50, pivoted t0 swing in a vertical plane.

In the form shown, each lever 50 is pivoted or fulcrumed at 51 on a suitable support in the lower part of the box. The levers 50 are Connected with a suitable actuating device, such as a pneumatic 52. In the particular form shown, the lower inwardly extending arms 53 of levers 50 are interconnected by a pin 54 which passes through a forked extremity'55 on one of the levers, which forked extremity straddles the extremity of the other lever and is slotted in order to receive said connecting pin. The connection between the levers 50 and the pneumatic 52 is preferably made by means of a. link 56, preferably of wire, connected at its upper end with the pin 54, and at its lower end with a pallet or valve 57 associated with the lid of the pneumatic. This valve is acted on by a leaf spring 59 carried by the lid or leaf of the pneumatic, and

said spring -normally holds the valve in position to close a relief opening or air inlet 58 in the lid of the pneumatic. The spring bears on a washer 57a surrounding the link 56 above the valve 57. The valve'or pallet is supported from beneath by a washer or projection 57b on the link, which guides the valve relatively to the air inlet without substantially obstructing said inlet. A screw G0 passing through the spring 59 permits the action of the latter to be adjusted so that the force by which the valve 57 is held seated may be varied for the purpose hereinafter described.

It will be evident from the foregoing description that as the pneumatic 52 is collapsed, the levers 50 will be swung on their pivots 51 in'such a way as to move the Hanges 44 of the take-up spool inwardly toward the edges of the note sheet in opposition to the springs 45. The pneumatic is exhausted through a tube 61 connected with suitable pressure reducing apparatus (not shown), the connection of tube 61 with the pneumatic being made by way of a small bleed opening 62, whereby the collapse of the pneumatic is retarded. Then the air is admitted to the pneumatic by the opening of the relief valve 57 or otherwise, the pneumatic is restored to the normal expanded condition by means of a spring 36 or similar device. The pneumatic is also normally held in the expanded condition by means of the springs 45 acting on the flanges 44 and the levers 50, as will be obvious. The tension of the spring 59 is greater than the force required to overcome the springs 45, and therefore when the device is not in use the flanges 44 are unyieldingly connected with the movable member of the pneumatic.

The operation of the mechanism will be more or less obvious from the foregoing de script-ion. The music spool 13 is first mounted between the spindles 15, 16 in the manner previously described so that the openings of the note sheet will coincide with the corresponding openings of the tracker bar. The pressure reducing' apparatus now being put into operation, the winding up` of the note sheet on the take-up spool is commenced by the usual mechanism and as the tube or conduit 61 of pneumatic 52 is connected with the pressure reducing apparatus, the pneumatic will collapse and the flanges 44 of the take-up spool will be forced inward against the edges of the note sheet. As the flanges 44 and levers 50 are symmetrically formed and located, the note 'sheet will be accurately centered on the take-up spool and caused to wind up tightly and truly. The flanges or movable spool members 44 do not contact with the edges of the note sheet until several layers have been wound on the take-up spool. This is due to the provision ofthe bleed 62, which delays the collapse of the pneumatic to the necessary extent. Thus, when the flanges 44 come inV contact with the edges of the sheet, their action is resisted by several layers of the note sheet, as well as by the springs 45. Thus, the pressure exerted on the edges of the sheet at this time is sufficient to center the sheet propeilly but not to tear or damage the same. The pressure exerted on the edges of the 'sheet by the flanges cannot increase to such an extent as to tear or injure the sheet because if the pneumatic is eX- hausted to a certain predetermined degree, the pressure of spring 59 is overcome and the lid of the pneumatic parts slightly from the pallet 57 so that further inward pressure of the flanges on the sheet is prevented. The spring 59 can be so set by means of its regulating screw as to determine the exhaustion of pneumatic which is sufficient to open the relief inlet by means of pallet 57, and therefore it is possible to so adjust the apparatus that the end flanges or members 44 of the take-up spool will not exert pressure on the note sheet in excess of a predetermined maximum pressure, which is variable at will. Then the pallet opens to admit air into the pneumatic through the relief i11- let, the parting of the pallet from its seat is only slight and momentary for the enspring as air seeps into Vthe instrument,

contact and constant pressure is most bene-.

ficial as it prevents side slipping and consequent loose winding of the note sheet on the vtake-up roll, and is of great aid in maintain- 1 ingby its guiding force correct registration between the perforations in the note sheet and those-of the tracker bar. As .the note sheet is thus wound upon the take-up spool in a compact vand orderly manner, it is naturally rerolled on themusic r'oll in such a condition as to induce proper operation the next time the music roll isplayed.

After rendition, the pneumatic 52 Yopens through the action of the springs 45 andthe so that the flanges of the take-up spooll are moved back toV their normal position. The

opening of the Pneumatic 52 may also be ,hastened by a relief valve 63, 6a connected with a tube and controlled by the music roll 13. In the particular form shown,the valve 63, 6e? is located on the back of the music box in .proximity to ,the lever 39 and when the music roll is taken out after rendi'- tion, the 'lever 39 will be automatically swung against the pivoted member 63 to open thereliefvalve and thereby admit air` tothe pneumatic 52 through tube 65 for the purpose of restoring the flanges 4A to their initial or inoperative position. 63, Gil is normally lieldclosed by a spring 63a ,acting on the swinging inember.

We do not claim herein the means for centering the music roll` longitudinally relatively to the tracker bar by the spindles having means engaging the outer faces of the rollV heads at the extremes of the over-all length of the roll, as claimed in our application Serial No. 106673.
